PROCESS OF MANUFACTURING CONCRETE COMPOSITIONS.

No Drawing.

To all whom it may concern:

Be it known that I, JAMES W. ADAMS, a citizen of the United States, and a resident of the village of Curtis, in the county of Frontier and State of Nebraska, (whose postofiice address is Curtis, in the said county and State,) have invented certain new and useful Improvements in Processes of Manufacturing Concrete Compositions, of which the following is a full and complete specification.

My invention relates to a process of manufacturing concrete compositions, and more especially for making artificial building blocks of concrete, and has for its object the provision of a process that will render the blocks made thereby impervious to water, frost-proof, and cause said blocks to have a maximum amount of tensile strength and crushing resistance.

In carrying out my invention, I employ, in a general way, a composition of materials substantially as follows: Five or six parts of sand (clean) and one part of cement' or, if gravel or broken stone is m addition to the above ingredients, I use three or four parts, ravel or broken stone two or three parts of sand lcleani, and one part of gem I mix all of the materials thoroughly and evenly in any desired manner with sufiicient water to give the composition the initial set. I then tamp the composition or compress it into blocks, by any wellknown form of press, until the composition is of sufficient density, then wet the same before removing from the press sufficiently to allow the moisture therein to come to and show freely on the surface. After the blocks have been treated as above stated they should be stored in a suitable building, where they will be protected from sun, rain, and wind, and allowed to remain for four or five days during which period, and as soon as all danger of washin is past they "should be watered or moistene such watering beingx continued at intervals, never allowing t em to become entirely dry, until a permanent set has taken place. They should then be ermitted to become entirely dry. The bloc s should then be removed to the open air and again watered until they shed the water, and then, finally, to get the best results, they should be permitted to dry for at least thirty days before using jj {more Cross Reference Patented Feb. 22, 1910.

consisting of the combination of determined quantlties of sand, cement, gravel or broken 7 stone, and amoistening agent, thoroughly mixing the same with the moistening agent, molding the resultant mass into blocks under pressure, moistening said blocks before removin them from the press sufiiciently to permlt the moisture therein. to come to the surface, removing said blocks from the press and storing them in a drying chamber where they will be protected from the sun, rain, and wind,-moistening said blocks until a permanent set has taken place, drying said blocks, removing said blocks from the drying chamber and again moistening them until they shed water and finally allowing them to dry thoroughly, substantially as specified. I In witness whereof I have hereunto set my hand in presence of two subscribing witnesses.
